Technical field
The invention belongs to natural drug and medicinal chemistry art and relate to novel tanshinone derivative, particularly 2-position alkyl
Or aromatic radical substituted Tanshinone I derivant, and prepare the method for these compounds, the compositions comprising this compound and
Prepare the purposes in antitumor drug.
Background technology
Tanshinone I (Tanshinone I), is again Radix Salviae Miltiorrhizae quinone I, chemical formula (1,6-dimethyl-phenanthro-[1,2-b] furan-
10,11-diketone), it is extracted from root and the stem of labiate Radix Salviae Miltiorrhizae (Salvia miltiorrhiza Bge).Tanshinone I, its
Pharmacological action is extensive, and Clinical practice scope is very big, can be used for treating coronary heart diseases and angina pectoris, myocardial infarction, viral myocarditis,
The treatment of the diseases such as arrhythmia, cerebrovascular, cerebral blood supply insufficiency, cerebral thrombosis, cerebral infarction, hepatitis, tumor, hypertension.
Therefore, scientists has carried out substantial amounts of research to following various tanshinone derivatives.
Owing to the water solublity of Tanshinone I is very poor, its in vivo bioavailability the lowest, so there being scientist to attempt Radix Salviae Miltiorrhizae
Ketone I carries out structural modification, to improve its water solublity and bioavailability, expands the medical value of Tanshinone I.(Qin Yinlin. Radix Salviae Miltiorrhizae
Ketone I derivant and application [P] the CN 1837199A.2006 in pharmacy thereof；Qin Yinlin. Tanshinone I derivant and in pharmacy

With and the experimentation of mechanism of action. practical tumor magazine, 2005,20 (1): 33-35).
It addition, studies have reported that the external propagation on SGC-7901 gastric adenocarcinoma cells of Tanshinone I and the impact of apoptosis.Real
Issuing after examination and approval existing, Tanshinone I has obvious inhibitory action, and its suppression to the growth of the SGC-7901 human gastric adenocarcinoma of In vitro culture
Cell grows within the specific limits, increases and inhibitory action enhancing with the concentration of Tanshinone I. (Zhou Xiaoli etc. Tanshinone I is to people
Gastric adenocarcinoma cells SGC-7901 propagation, the impact of apoptosis. modern medical oncology, 2011,19 (3): 423-427).
Although a lot of with bioactive research to the structural modification of Tanshinone I, but there is not yet good water solubility, toxicity
The synthesis of the antitumor tanshinone compound that low and biological activity is high and the report of application.
